Product Summary
The LT1073CS8#TR is a versatile micropower DC/DC converter. The device requires only three external components to deliver a fixed output of 5V or 12V. The very low minimum supply voltage of 1V allows the use of the LT1073CS8#TR in applications where the primary power source is a single cell. An on-chip auxiliary gain block can function as a lowbattery detector or linear post-regulator. The applications of the LT1073CS8#TR include Pagers, Cameras, Single-Cell to 5V Converters, Battery Backup Supplies, Laptop and Palmtop Computers, Cellular Telephones, Portable Instruments, 4mA to 20mA Loop Powered Instruments, Hand-Held Inventory Computers, Battery-Powered a, b, and g Particle Detectors.
